Why can Chardonnay predict weather changes?

Before and after sunrise and sunset, the sky is sometimes dyed red or orange-red, which is Chardonnay. What appears in the morning is called sunrise and what appears at night is called sunset.

How did Xia Xia come into being? At sunrise and sunset, sunlight can only reach the sky near the horizon through a thick layer of gas. When sunlight passes through the atmosphere, purple light and blue light are scattered badly because of the short wavelength, and there is little left when they reach the horizon. The remaining light is only red, orange and yellow with longer wavelengths. After these rays are scattered by air molecules, water vapor and dust impurities above the horizon, we can see colorful and picturesque rosy clouds.

The more moisture and dust impurities in the air, the brighter the color of rosy clouds. If there are clouds in the sky, they will also be "dyed" in bright colors.

On August 23rd, 1883, a strong volcanic eruption occurred on Krakato Island in Nishi. The ejected ash is about 65.438+08 billion cubic meters, and a large amount of fine dust rises to an altitude of 70,000 to 80,000 meters, which permeates the sky for a long time. So that year, the rosy clouds seen all over the world were particularly bright and beautiful, and people called them "blood clouds".

Because the color and brightness of Chardonnay are related to the content of water vapor and dust in the atmosphere, the color and appearance of Chardonnay are indicative of the weather changes. As the saying goes, "Don't go out in the morning, travel thousands of miles at night", that is to say, the morning glow means rainy day, and the sunset glow means sunny day.
